Applications Dehumidification by cooling or dessication has a variety of applications, including: Preventing moisture regain. Nearly all materials have some affinity for moisture based on surface characteristics and the amount of surface exposed to humid air. Moisture regain occurs when…
In many plants that batch-blend bulk products, weigh batching is a manual, time-consuming operation in which ingredients are weighed individually before being discharged to a blender or some other process vessel. A significant number of such plants could benefit from…
An automated spreadsheet method can quickly help minimize fresh hydrogen consumption while maximizing hydrogen recovery and reuse in petroleum refineries and petrochemical complexes In petroleum refineries and petrochemical complexes, there are many hydrogen consumers, such as hydrotreaters, hydrocrackers, isomerization units…
Carbon capture and storage (CCS) is an area of technology that has received national and international attention. CCS is seen by some as a way to reduce carbon dioxide (CO2) emissions into the atmosphere and thereby decrease the threat…
To many, the concept of a "smart plant" involves integrating critical process subsystems and instrumentation with the goal of streamlining operations, increasing production and, simply put, making more money. But looking at the bigger picture, the true goal of having…
Accurate temperature measurement is not difficult. It does, however, require you to think about accuracy from specification and selection, all the way up to installation and operation of your temperature-measurement sensor. There are opportunities to improve accuracy during each of…
FIGURE 1. In a typical system for wastewater treatment, the liquid feed is introduced at the top of the column and steam is introduced at the bottom In recent years, steam strippers have become integral parts of industrial plant…
Most common acids can be stored in horizontal or vertical ASME-type tanks, as shown in the figures to the right, or vertical API-type tanks. Horizontal, carbon-steel ASME-type tanks of 10,000 — 40,000 gal capacity should have a plate thickness of…
Effective use of capital in the ownership and management of manufacturing assets is critical to the financial performance of companies in the chemical process industries (CPI). Many of these companies use benchmarking in compliance with applicable laws and antitrust…
A. Alexander and F. Muzzio, Rutgers University Proper blender selection can improve the mixing of bulk solids. Be sure to consider post-blending segregation problems Mixing and blending of bulk solids occurs frequently in many industrial processes. Though small-scale mixing and…
